An attentive use of this control will give you a very wide panorama of sound effects. +10dB 8 - 5 +10dB LEVEL 5 MON (AUX1) Control APM80.1000 has two auxiliary sends which can be used for sending signals to external or internal effects device or for creating a monitor mix, they are used to adjust the level of respective channel signal sent to AUX bus, and the adjustable range goes from - to +10dB. The AUX1 control is configured as PRE-FADER, which means that the signal is sent out before reaching the channel fader. It is used for a monitor mix in a live sound mixing, or for a headphone mix in recording application. 6 DSP/FX (AUX2) Control The AUX2 control is configured as POST-FADER, so the audio signal will be affected by channel fader. Via the AUX2 OUT jack, the AUX2 signal can be sent to an external effects device, furthermore, the AUX2 signal can also be assigned to internal onboard effect module. 7 PAN Control Abbreviation of PANORAMA control for mono and stereo channels. It is used to determine the amount of channel signal sent to left and right of main mix. Keep this control in center position, then the signal will be positioned in middle of stage. Turn this control fully counterclockwise, the signal will be present only on the left of main mix and vice-versa. 8 Channel LEVEL Control This control is used to adjust the overall level of respective channel. The adjustable range goes from - to +10dB. 4.2 MASTER SECTION Controls 12 9 10 11 9 STEREO GRAPHIC EQ APM80.1000 is equipped with both stereo graphic EQs, one is for MAIN MIX; another for MONITOR MIX, each of them provides 9-band fader controls. Via these faders, you can boost or attenuate the selected frequency by 15dB at a preset bandwidth. When all faders are at the center position, the output of the equalizer is flat response. They are used to modify the frequency "contour" of a sound. The EQ function will be activated automatically as soon as you operate APM80.1000. 10 FEEDBACK TERMINATOR Button (MONITOR MIX) Pressing this button the automatic feedback detection function will be activated in monitor signal path. When a frequency band fader lights up, it means the level of this frequency band is too high, i.e. there is a little feedback occurring in this frequency band, which may result in unpleasant speaker "howling" or " whistling " . In this case, in order to eliminate feedback, you need to turn down the corresponding fader. 9 11 MONITOR LEVEL Control This control is used to adjust the level of monitor output. 12 MONITOR LEVEL LED Display This LED display is used to monitor the monitor output level. 15 9 13 14 13 FEEDBACK TERMINATOR Button (MAIN MIX) Pressing this button the automatic feedback detection function will be activated in main mix signal path. When a frequency band fader lights up, it means the level of this frequency band is too high, i.e. there is a little feedback occurring in this frequency band, which may result in unpleasant speaker "howling" or "whistling" . In this case, in order to eliminate feedback, you need to turn down the corresponding fader. 14 MAIN MIX LEVEL Control This control is used to adjust the overall volume of main mix output. 15 MAIN MIX LEVEL LED Display The stereo 4 segments LED display is used to monitor the main mix output level. 16 16 OPERATING LED Display The LED indicates when the power is switched on in APM80.1000. 10 17 PHANTOM 48V Switch It is available only to the XLR MIC sockets.

INSTALLATION AND CONNECTION Ok, you have got to this point and you are now in the position to successfully operate APM80.1000. However, We advise you to read carefully the following section to be the real master of your own mix. Not paying attention enough to the input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow this procedure for every single channel: Turn down all input and output gain controls. Connect phantom powered microphones before switching on the +48Volt phantom power switch. Set the output level of APM80.1000 or the connected power amplifier at no more than 75%. Now, set the MONITOR level at no more than 50%. In this way you will be able to hear later what you are doing connecting a pair of headphones or a pair of powered studio monitor speakers. Position EQ controls on middle position. Position panoramic (PAN) control on center position. Increase the input gain properly for maintaining the good headroom and ideal dynamic range. Depending on the actual application, turn slowly the input and output level controls for obtaining the maximum gain before distortion. Now repeat the same sequence for all input channels. The main LED meter could move up into the red section. In this case you can adjust the overall output level through the MAIN MIX control. 6.1 Audio Connections You can connect unbalanced equipment to balanced inputs and outputs.
